Resumo
The use of unconventional food for animals is becoming more common. The objective was to evaluate the inclusion of Madagascar cockroach (Gromphadorhina portentosa) meal in the diet of cockatiel (Nymphicus hollandicus) chicks in captivity. Twenty-eight cockatiel chicks were used during 90 days of experiment. The animals were divided into two groups: a control group (receiving commercial feed + seed mixture) and a test group (receiving a control diet supplemented with Madagascar cockroach meal). The cockroach meal was mixed into commercial feed at a ratio of 14:1 (commercial feed: cockroach meal; 6.6% inclusion). Parents of the chicks were fed the experimental diets 30 days before egg laying to evaluate the influence of the cockroach meal on offspring development in the nest (1 to 30 days of age). Body development of the birds was evaluated every three days from the first to the 30th day of age and then every 15 days from the 31st to the 90th day of age. The cockroach meal did not influence (P > .05) the growth characteristics, body weight, total length or length of the animal's beaks, wings or tails, but increased seed consumption from the 31st to the 90th day of age. It is concluded that the cockroach meal can be used in the diet of growing cockatiels at an addition level of 6.6%.
